The Eternals are one of the few races who survived the awakening of the Gods and the fall of Prime Creation. They were solitary, but powerful, weavers of essence and were locked in a bloody war with the Other Ones, another race which survived the Gods.

Even though the Gods struggle so, their achievements are temporary at best.
For all beings must dream, and within those dreams dwell the Dreamer.

Come then and succumb to the lord, come then and enter the realm of sleep.
Come then taste the nectar, made of the tears of the dreamer.

-The 5th verse in the Book of the Dreaming Cult
